590 Circulation Research September 1, 2017 pathophysiology, there is still a significant gap in our current knowledge about how stress-related signaling contributes to protein aggregation. At conceptual level, the study reported here by McLendon et al4 has revealed an interesting, new, and potentially very important molecular path linking JAK1-mediated stress signaling with protein aggregation. However, this is still a preliminary finding at its very early stage, and many questions remain to be fully addressed. First of all, the current study only tested the effect of JAK1 on the formation of protein aggregate but not on the dissolution of the established protein aggregate. This is an important leap needed to be fulfilled to fully demonstrate the therapeutic potential of targeted JAK1 inactivation. The current study also raises questions about how JAK1-mediated signaling alters protein degradation capacity via proteasome pathway, and whether it involves canonical JAK/STAT-mediated gene regulation or a noncanonical process independent of STATs. The current validation study was conducted only in an in vitro model system using neonatal myocytes in culture, whereas further in vivo evidence would be critical to support the physiological and translational relevance of this finding. Nevertheless, the report by McLendon et al4 showcased again the power of an unbiased genome-wide analysis to uncover novel molecular pathways and gene–gene interactions. In fact, among the 14 high-confidence hits from the screening, several signaling molecules other than JAK1 were also identified, including casein kinase 1 γ 2, Ptprv (a transmembrane tyrosine protein phosphatase), and CDC42 binding protein kinase α. Each of these candidate genes may contribute to a different aspect of the underlying regulatory network leading to protein aggregation. There are indeed a lot of work ahead of us to untangle this complex web of regulatory network in protein aggregation and proteotoxicity before we can untangle a broken heart.
